Energy Transfer Partners LP said it will build a natural gas pipeline linking the Marcellus and Utica shale formations to markets in the U.S. and Canada.

The first 400-mile segment of the pipeline will carry 2.2 billion cubic feet a day, the company said today in a statement. The project may be expanded to carry up to 3.25 billion cubic feet.

The three largest shippers on the project are Antero Resources Corp., Range Resources Corp. and American Energy Partners LP, the drilling company formed by Aubrey McClendon, who was dismissed from Chesapeake Energy Corp. in a shareholder revolt.
